Solenoid valve for air and neutral gases
DN 80 | VRA/VRL
Elettromeccanica Delta
The VRA/VLA/VTA types are normally closed
solenoid valves for cold combustion air regulation.
When not energized the spring works on the disc
keeping the minimum passage of air.
When powering the coil the valve opens, moving
the disc to the maximum open position.
When power is switched off the valve rapidly
moves to the minimum position.
This type of device is suitable for high/low stage
control of combustion air in industrial gas burners.
(qualified for continuous service- 100ED).
